Mesoscale Discussion 0986
NWS Storm Prediction Center Norman OK
0436 PM CDT Sun May 26 2024
Areas affected...Western Virginia
Concerning...Severe potential...Severe Thunderstorm Watch likely
Valid 262136Z - 262330Z
Probability of Watch Issuance...95 percent
SUMMARY...Downstream severe thunderstorm watch issuance will be
needed within the next 30 minutes to address an approaching MCS.
DISCUSSION...A well-organized QLCS continues to push east across the
southern Appalachians and has a history of producing damaging (50-60
mph) winds. GOES imagery shows that this line continues to produce
robust embedded updrafts despite moving into a region with weaker
deep-layer shear. This may be due to compensating effects from
higher SBCAPE on the eastern side of the Appalachians. Given the
buoyant air mass and steep low-level lapse rates downstream, the
severe/damaging wind threat should continue. Watch issuance is
likely within the next 30 minutes.
